Changelog formatting

[hipstersmoothie]

What Changed

This PR addresses a few things about how the changelogs are formatted:

• Fix extra space in "Push to master" changelog title
• Strip consecutive whitespace in PR titles/commit messages
• Add newline to end of new changelogs

There still might be a chance for a changelog to have bad formatting (ex: release notes).
To fix this would would have to depend on prettier and formate the PR/commit bodies as well.
I don't really want to do that.

I also ran the formatting over all committed changelogs.

Why

closes #1186
